the fr-FR.localise.php

This file should be present at least in site zip

Explanation of this file: It replaces the fr-FR.ignore.php and it can be customized depending on languages.

Ignore search words.

Define upper and lower limit of search words length.

Define number of characters to display for the result of the search.

Define specific plural functionality for some languages where the value of the string can change depending on the count (Russian for example).

Define custom transliteration (i.e. when NOT using the Unicode URLS parameter in Global Configuration) to ensure proper change of some alphabets to ascii for the alias used when SEF is on. (The transliteration which is now default in 1.7 should take care of all latin-based languages.)

Define a custom calendar by adding a function as well as some js files

ALWAYS SAVE THIS FILE AS UTF8 NO BOM if it contains non-ascii glyphs (accented letters, etc.)
